The Impulse Voltage Generator is used to test the insulation and protection performance of various high-voltage electrical equipment
The Impulse Voltage Generator is used to test the insulation and protection performance of various high-voltage electrical equipment under the action of lightning overvoltage,operating overvoltage,and other impulse voltages.The test voltage is much higher than the voltage that the equipment insulation can withstand during normal operation.Many high-voltage electrical equipment must undergo Impulse Voltage Generatoring during factory testing,type testing,or after major repairs.The impulse voltage generator is also one of the basic equipment in high-voltage laboratories.With the continuous improvement of transmission voltage levels and the widespread application of large capacitance electrical equipment such as cables,the output voltage and energy of the impulse voltage generator are also constantly increasing.
The Impulse Voltage Generator is divided into lightning Impulse Voltage Generator and operational Impulse Voltage Generator,and lightning Impulse Voltage Generator is further divided into full wave withstand voltage test and truncated wave withstand voltage test.
Common methods for Impulse Voltage Generatoring
Common Impulse Voltage Generator methods include:positive half wave withstand voltage test,negative half wave withstand voltage test,DC withstand voltage test,and waveform withstand voltage test.These methods can evaluate the insulation performance,voltage resistance,and anti-interference ability of equipment.When conducting testing,it is necessary to select appropriate testing instruments and parameters based on specific requirements,and ensure the safety of testing equipment and environment.The test results need to be recorded and evaluated.
The following are several common methods for Impulse Voltage Generatoring:
1.Positive half wave withstand voltage test:In this test,high-voltage pulses are applied to the tested equipment in the form of positive half waves.This testing method is mainly used to evaluate the insulation performance of equipment,test the voltage resistance of insulation materials and electronic components.
2.Negative half wave withstand voltage test:Similar to positive half wave withstand voltage test,except that high-voltage pulses are applied to the tested equipment in the form of negative half waves.This testing method is mainly used to evaluate the insulation performance of equipment under grounding conditions.
3.DC withstand voltage test:This test method applies a stable DC voltage to the tested equipment to evaluate its insulation performance and withstand voltage capability.DC withstand voltage test is commonly used to evaluate the electrical performance and reliability of equipment during long-term operation.
4.Waveform withstand voltage test:This test method applies specific waveform signals(such as pulses,sawtooth waves,etc.)to the tested equipment to simulate the voltage surge that the equipment may encounter during actual operation.The waveform withstand voltage test can evaluate the anti-interference ability and response ability to voltage changes of the equipment.
